Question

我有一个XML文档，如下所示：

<Patient>
    <Treatment>
        <Medications>
            <Medication>
                <MedicationCode>X</MedicationCode>
            </Medication>
        </Medications>
        <Procedures>
            <Procedure>
                <ProcdName>A</ProcdName>
            </Procedure>
            <Procedure>
                <ProcdName>B</ProcdName>
            </Procedure>
        </Procedures>
    </Treatment>
</Patient>

转换后应该如下所示：

<Patient>
    <Procedures>
        <ProcdName>A</ProcdName>
    </Procedures>
    <Procedures>
        <ProcdName>B</ProcdName>
    </Procedures>
</Patient>

我设法做到了，但只使用了4个不同的XSL转换：第一个用于删除Medications元素，第二个用于删除处理元素但保留其内容，第三个用于删除Procedures元素，第四个用于删除将Procedure元素重命名为Procedures。当我尝试在一次转换中完成所有操作时，只有其中一些生效。是因为他们都在修改相关元素吗？有没有办法通过一次转换实现这一切？

为了更清楚，这些是我正在使用的XSL，正如我所说，它们确实给了我正确的输出，但只有当它作为4个单独的转换运行时。 XSL1：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" />    
<xsl:strip-space elements="*"/>
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template> 
    <xsl:template match="Absences"/>
    <xsl:template match="Sensitivities"/>
    <xsl:template match="DiagDate"/>
    <xsl:template match="DiagStatus"/>
    <xsl:template match="DiagSide"/>
    <xsl:template match="DiagCertainty"/>
    <xsl:template match="DiagSPerformer"/>
    <xsl:template match="DiagCreated"/>
    <xsl:template match="DiagPriority"/>
    <xsl:template match="DiagSolved"/>      
    <xsl:template match="Medications"/>         
    <xsl:template match="ProcdValidity"/>
    <xsl:template match="ProcdClass"/>
    <xsl:template match="ProcdStatus"/>
    <xsl:template match="ProcdPerformer"/>
    <xsl:template match="ProcdSide"/>
    <xsl:template match="ProcdCreated"/>                
    <xsl:template match="Parameters[Parameter/ParameterCode='31']"/>        
</xsl:stylesheet>

XSL2：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" />    
<xsl:strip-space elements="*"/>
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match ="Treatment">
    <xsl:copy-of select="node()"/>
    </xsl:template>                 
</xsl:stylesheet>

XSL3：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" />    
<xsl:strip-space elements="*"/>
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template> 
    <xsl:template match ="Procedures">
    <xsl:copy-of select="@*|node()"/>
    </xsl:template>     
</xsl:stylesheet>

XSL4：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" />    
<xsl:strip-space elements="*"/>
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template> 
    <xsl:template match="Procedure">
    <Procedures><xsl:apply-templates select="@*|node()" /></Procedures>
    </xsl:template>         
</xsl:stylesheet>

很抱歉这个故事很长，但我对XSL很新，看起来我无法解释我的问题。谢谢。

Answer 1

这个简单的样式表应该这样做：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <!--
    Whenever you see one of these elements, only apply the rules for all
    child elements of that element, but don't copy the element itself
    into the output.
    -->
    <xsl:template match="Treatment | Procedures">
        <xsl:apply-templates/>
    </xsl:template>

    <!--
    Use an empty template to omit an element from the output completely.
    -->
    <xsl:template match="Medications | Parameters | Absences | Sensitivities"/>

    <!--
    For every <Procedure> element, create a <Procedures> element.

    Apply the templates for the selected child elements. In this case, the
    template that matches each of <ProcdName>, <ProcdCode> and <ProcdDetail>
    is the identity template (see below), so those nodes are copied into the
    output XML as is.
    -->
    <xsl:template match="Procedure">
        <Procedures>
            <xsl:apply-templates select="ProcdName | ProcdCode | ProcdDetail"/>
        </Procedures>
    </xsl:template>

    <!--
    XSLT identity transform. The XSLT processor applies this template for
    every node in the source document that doesn't match a more specific
    template (that is, a template with a higher priority).

    See:

    https://en.wikipedia.org/wiki/Identity_transform
    http://lenzconsulting.com/how-xslt-works/#conflict_resolution_for_template_rules
    -->
    <xsl:template match="@* | node()" name="identity">
        <xsl:copy>
            <xsl:apply-templates select="@* | node()"/>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>

我可以使用一个XSLT为元素内容创建一些不同的更改吗？
